“”Can any medical types posit a theory?””
I’m not a medical type but my sister in law had the same problem and it was lung cancer... She thought it was a cold; traveled to CA from the Midwest for a funeral and saw a doctor finally when she came home. She was a smoker and as far as I know Hillary isn’t but it wouldn’t be the first time a non smoker had lung cancer.. She fought and won against cervical cancer years before but couldn’t beat lung cancer. The treatment was so brutal, she couldn’t take any more of it and stopped it.
A haiku, spurred by you:
Sad to say it
But if Hill dies from cancer
America wins
